Escape from Michigan Central Station

You are a tourist and you are on a trip to US. You wanted to go to Michigan Central Station and you are right there. That is where you were supposed to join the other tourists who would be taken around by a guide. You do not see anyone at the station and that is an unpleasant surprise for you. The situation becomes more anxious for you when you realize that you have come to the old Michigan Central Station and you are lost here. You must be quick to find a way to get out of here and reach the correct place.
